There's two GPS approaches into KDMW; the RNAV (GPS) RWY 16 and the RNAV

Both start from off-airway IAF's, with no feeder routes. Both use the
same missed approach fix. Yet, one is marked "Radar Required" and the
other isn't. Anybody have any clue why?

Secondary question -- I thought the concept of these pure GPS approaches
was to lay out 3 IAF's in a T pattern. Why no outside IAF's, and no PT?
Both of these seem kind of ugly if you start them from a course 180
degrees off the FAC.

Is FOUST on an airway? If it isn't then the facility needs to use at least
a radar monitor to get you there.

As to the "T" design, that is the design objective, but in crowded airspace
like that the ATC folks probably told the procedures designers "Don't do
that here."
